SPECIFICATION forming part o Letters Patent No. 386,035, dated July 10,1888.

Application tiled October l2, 1887. Serial No. 5252.167.

.To all whom it may concern:

Be it known that I, SAMUEL D. BUEGEL, a citizen oftheUnitedStates,residingatThomasville, in the county of Thomas and State ofGeorgia, have invented a new and useful Im provenient in Machines forSawing Fence- Piehets, of which the following is a specification.

)Iy invent-ion relates to an improvement in machines for sawingfence-pickets; and it consists in the peculiar construction andcombination of devices,that will be more fully set forth hereinafter,and more fully pointed out in the claims,

In the accompanying drawings, Figure l is a side elevation of apicket'sawing machine embodying my improvements. Fig. 2 is a top planview of the saine. Fig. 3 is an end elevation. Fig. t is a verticaltransverse sectional view taken on the line .r a: of Fig. l. Fig. 5 is adetail perspective view ofa board, showing the lines on which thepickets are sawed. Fig. Gis a similar view of one of my improvedpickets.

A represents the corner posts or standards of a frame or table.

B represents two pairs of crossed beams, which connect the posts A. atopposite ends.

G represents a pair of longitudinal bars, which are arranged on oppositesides of the table or frame, and connect the posts or standards A neartheir lower ends.

I) represents a pair of similar bars, which are attached to the posts orstandards A at their upper ends, and are arranged parallel with the barsC.

E represents a longitudinal central beam, which is beveled on oppositesides, as shown, corresponds in length with the table or frame, and isprovided at its ends with vertical depending standards F. The saidstandards are provided with vertical slots G, and the lower ends ofthesaid standards are secured in vertical grooves H, which are made on theouter sides of the crossed bars B at the centers thereof.

I represents bolts, which extend through openings in the centers of thecross-bars, and also extend through the slots G in the standards F.Clamping-nuts K are screwed onto the outer ends of the said bolts, andare adapted (No model.)

to be compressed against the outer sides of the standards F, so as tosecure the said standards at any desired vertical adj ustment, andthereby enable the beam E to be secured at any desired height.

'L represents a guide-rail, which is secured 0n the upper side of thebeam Eat the center thereof, and extends longitudinally on the saidbeam` The opposite sides of this guide-rail L are beveled upwardlytoward each other, asshown, at an angle of about thirty degrees. Nearthe center of the guiderail and near the center of the beam D is averticallongitudinal opening M.

N represents a metallic flange-plate, which is secured in a verticallongitudinal slit or kerf that is made in the guide-rail at the rear endthereof. The upper edge of this dangeplate projects a suitable distanceabove the upper edge of the guide-rail, as shown. On opposite sides ofthe guide-rail, at the rear end thereof, are arranged guide-blocks O,which have their upper edges provided with incised angular grooves P.Vertical slots R are made in the said guide-blocks, and screws er boltsS extend through the said slots and enter the sides of the guide-rail E,and thereby secure the guide-blocks to the said guide-rail at anydesired vertical adjustment.

T represents a pair ot' longitudinal bars, which have their endsarranged on the upper inclined sides of the crossed bars B, the saidbars T being arranged with their upper sides at right angles to thebeveled sides of the guide-rail L. Vertical transverse slots U are madein the bars T, near the ends thereof.

V represents bolts which extend through the upper crossbars, B, andextend through the slots U. Clamping-nuts W are screwed on the upper endof the said bolts and bear against the upper sides of the beams T, andthereby secure the said beams or bars on the upper sides of the crossedbars B and permit the said beams or bars T to be adjusted laterallytoward or from the central beam, E. On the upper sides of the bars T, atsuitable distances from the rear ends of the said bars, are securedbearingblocks X.

Y represents a pair of saw-arbors, which are journaled in the saidbearing-blocks, and are inclined parallel with the upper sides of IOOthe bars T. rilhese arbors are out of line with each other, as shown,and to their inner ends are secured circular ri psaws Z, which arearranged on opposite sides of the guide-rail L and at a suitabledistance therefrom, and are parallel with the said inclined sides of theguide-rail, as shown. The upper edges of these saws extend into recessesor notches which are made in the upper edge of the ilangeplate N. To theouter ends of the sawarbors are secured bandpulleys A. In the outersides of the bars D of the frame, near the centers of the said bars, aremade vertical grooves B'.

C represents hangers, which have vertical arms secured in the saidgrooves by means of screws or bolts D', which work in vertical slotswith which the hangers are provided.. The lower ends of these hangersform bearings for a saw-arbor, E', which extends transversely across theframe. To the center of this shaft is attached a circular rip-saw, F',the upper edge of which extends through the opening M.Thesaw-arborpassestransverselythrough a groove, G', ou the lower side ofthe beam E, and thereby permits the said beams to be vertically adjustedwith relation to the saw-arbor. By reason of the slotted hangers inwhich the saw-arbor is journaled the latter may be also verticallyadjusted, as may be readily understood. H' represents a band-pulley,which is secured on one end of the arbor E'.

V I represents a driving-shaft, which is journaled in bearing-boxes.secured on the upper edges of the bar C, near the front end of themachine. To one end of this shaft is secured a pulley, K', for thedriving-belt, (not shown,) and to the opposite end of the said shaft issecured a pulley, L', which is connected to the pulley H `on the arbor Eby means of an endless belt, M. N' represents a pair of pulleys, whichare of the same diameter as the pulley L', are secured to the shaft I'on the inner sides of the bar C, and are connected to the pulleys on theinclined saw-arbors by means of endless belts O, which bear againstguidingsheaves O2.

P' represents aguide-board,which is secured on one side of the guiderail by means of screws or `bolts R', which pass through vertical slotsS' in the lower edge of the guideboard and enter one side of theguide-rail.

T represents a brace, which connects the upper edge of the guide-boardto a block on the upper edge of one of the bars D, and thereby securesthe said guideboard rigidly in position.

The pickets, for the manufacture of which my savving-machine isdesigned,are -veledon opposite sides to feather edges b. f

The operation of my sawing-nachine and the method of making the picketsare as follows: A-board, c, of suitable length, Width, and thickness, isfirst provided with an incised groove, d, on its lower edge, adapted tot on the upper edge of the guide-rail L. The board is then placed inposition on the upper edge of the said guide-rail L, and is caused tobear against the guide board P', and is forced forward on the saidguide-rail and presented to the action of the saw F', which makes thelongitudinal vertical kerf in the center of the board, from end to 'endthereof, and thereby partly splitsthesaid board. As

the board is forced forward over the upper,

the board, and thereby serves to separate a diamond-shaped picket fromone side of the board. When the board reaches the inclined saw Z on theopposite side of the guiderail, the said inclined saw ents a similarkerf i-n the board,and thereby serves to separate another inclinedpicket from the opposite side thereof. While the pickets are being sawedfrom the board, their outer ends, as they pass beyond the inclinedsa\vs,are guided in the groovesin the upper edges of the guideblocks O,and on the under sides of downwardly-inclined wings Owith which a guide,O, iis provided.

From the foregoing description it will be understood that the board isiirst ripped on a central line, and is then cut on inclined lines ofcleavage, extending from the central cut or kerf. The said central cutor kerf forms one side of each picket, parallel outer sides of the boardform oneside also ofthe said pickets, and the remaining parallel sidesof the pickets are formed by the inclined kerfs. The cutting portions ofall the saws intercept each other in the same longitudinal vplane of themachine, so that the inclinedsaws will cut through the board to thecentral kerf. The formation of the picket and separation of the samefrom the board are thus rendered perfect and certain. By thus dividingthe board in the center and forming the pickets by making inclined kerfson opposite sides of the central dividing-kerf I am enabled to maketwice as many pickets from a board of given size than it has beenheretofore possible to manufacture from the said board, therebyeffecting a very great economy of lumber.

Pickets which are` made diamond shape in cross-section, as hereinbeforedescribed, are strong and light, and are specially adapted to be securedbetween twisted wires to form the combined wire and picket fences whichare now in extensive use. It will be readily observed that pickets thusconstructed may be painted with much greater facility than ordinarypickets, for the reason that there are no opposing edges of the saidpickets to which to apply the brush, as the beveled sides of the picketsconverge to form feather edges, and thereby only formtwo oppositesurfaces to which the paint can be applied. By thus bev IIO ISO

eling the sides of the pickets and rendering them diamond shape thesuperficial area ot' the pickets is lessened, and consequently a smallerquantity of paint is required to cover them.

Having thus described my invention, I claim l. In a machine i'or sawingpickets, the co1nbination ot' the saw F', and the saws Z on oppositesides of the saw F and vertically inA clined in opposite directions, andal1 having their cutting portions intercepting each other in the samelongitudinal plane, the saws Z and F being out of line with each other,substantially as described.

6. The combination, in a machine for sawing pickets, of the guide-railE, a circular saw, F', having its upper edge extending through a centralopening in the guide-rail and projecting above the same, the inclinedcircular saws Z on opposite sides ofthe guide-rail, and the guide-boardP, arranged on one side of the guiderail, substantially as described. 7.In a machine forsawing pickets, thecombination of the saw F, for cuttingthe longitudinal kerf in the board, with the verticallyinclined saws Z,arranged on opposite sides and in rear ofthe saw F', said saws Z cuttinginclined kerfs in the board, the cutting portions oi' the saws F Ziutercepting each other in the same longitudinal plane, substantially asdescribed.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence oftwo witnesses.
